Bug ID: 21934
Summary: gas build fails when using gcc 7
Product: binutils
Version: 2.29
Status: UNCONFIRMED
Severity: normal

Component: gas

Fix a gas build error when using gcc 7
I found this only when doing an ARM-to-x86_64 cross-toolchain build, but I
presume it can occur in other circumstances as well.
When using gcc 7, config/tc-i386.c fails to compile because of a compiler
warning:
In function 'output_invalid':
9719:12: error: '%x' directive output may be truncated writing between 1 and 8
bytes into a region of size 5 [-Werror=format-truncation=]
This is similar to other issues I found corrected in binutils 2.29, e.g. PR
21096, and I was able to fix it similarly by increasing the size of the buffer
slightly. Patch attached.
